Writing this article is purely a record of your own CCIE experience. Every CCIE is a storyteller. No matter what the content of the story includes, you should be hardworking and persistent.
I started preparing for the CCIE RS exam in January 2018. The first year is to learn, review, and consolidate some CCIE theoretical and experimental courses. I started practicing lab in August and lasted for 17 months. I finally passed the CCIE RS exam in Beijing in April 2019. Although the number is very late, it is also a kind of road on my way for many years. Recognized, still very happy.
First of all, let's talk about the exam. The exam and the actual work are completely different. The technical content of the exam is very old and very narrow, but it is very deep. It takes a lot of effort to master all of it. The lab stage is practiced day and night. It is certain that nothing can be done during this time. The practice, during the weekend of the week, is all the time to practice, other activities are really suspended. As far as the current version of CCIE5.0 is concerned, the amount is really too big. It is really not easy for people who can persist. I basically do 4 hours of lab exercises in the latter day and 8 hours per day on weekends. Exercise. The lab of the current 5.0 exercise is rough as follows:
Lab a total of 5 sets lab1, lab1+, lab2, lab2+, lab3 (increasing geometric difficulty)
TS has 4 sets TS1, TS2, TS3, TS4
DIAG 2 sets D1, D1+
Among them, the lab part is the most difficult, and the time consumed is also the longest. At first, a set of lab takes about 2 weeks to complete the knocking, and the correct rate of the previous knocking is also low, and the level of the exam is 4 After knocking in the hour and the correct rate is above 90%, TS can be easier (just relative) than Lab, but it also requires a lot of practice to get familiar with it. DIAG needs pure memory. This week is a week before the test. Time is more than enough.
The examination is divided into three parts: the above LAB, TS, DIAG, each part of the score must be more than 80% to pass this part, and the total score of the three parts must be added to reach more than 80% of the total score. Exams, that is to say if the three divisions pass, but the total scores do not reach the pass line, they can't pass the exam. Therefore, it is necessary to take a high score to be insured as much as possible. After all, the examination fee is very expensive and the energy is a lot of effort. If you can't pass your confidence in one time, it will be very big. Let's go to the exam. I went to the Beijing test room. I took the test on the 8th floor of Yintai Building C. It started at 8:00 in the morning and ended at 4:30 in the afternoon (TS has 2.5 hours, DIAG half an hour, and the rest of the time LAB). 15 minutes of mealtime (the examiner will bring meals, lunch is tasted in general). There are no restrictions on the number of entrances and exits in the middle of the exam. The questions I got on the day were TS2+, DIAG2, LAB3, and the TS and DIAG parts ended very smoothly. Part of the demand for multicast is stuck because the problem of BGP routing cannot be caused. After trying various solutions, it still can't be solved. It simply restarts several devices, which leads to the demand point that was completed before. There was an error in the test phenomenon (because the BGP route converges slowly after the device restarts and resumes after the convergence is completed). It is considered to be the examiner TR. Later, if there is no problem, it will be automatically restored after waiting for a while. Khan), but the problem of multicast still can't be solved. I can only give up this point and bite the bullet. Later, when I came home and performed the same configuration discovery in the practice environment, it was achievable, so it was suspected that the virtual machine in the examination room caused some unknown problems. There is also a small episode in the middle that is the examiner TR (generally TR is around 2:30 pm), so I found it in time and checked it out. Out of the examination room, I rushed to catch the high-speed rail, because the multicast problem was not fixed, plus the lack of time is not enough to check again if there are other points being examined by the examiner TR, my heart is a bit uneasy all the way, good to 9: At the time of 30, the result showed PASS, which put a hanging heart down.
Because the version is a bit too bad now, plus Cisco will limit the pass rate (change), resulting in a relatively small number of people currently in the exam (the position is not very tight, you can book the test position in the month), blocking the version of the practice Not recommended. Although a large number of exams only take 1-2 labs in a certain period of time, it is very likely that the lab that you are not familiar with will probably hang up because I had a classmate because The work was very busy, and the focus was on the two versions of the regular test. At that time, most exams were lab2+ and lab3, but when I took the exam, I got the lab1+. The result was that I hanged, so the gambling must be lost. Still have to be well prepared, it is necessary to look at the recent reports of other candidates before the exam, because the underlying environment of the examination room is likely to change, the demand may change at any time, sometimes because of these small points If there is no GET, it will lead to a problem that is not fixed, which will affect the performance of the entire exam. In particular, the small change point of TS often leads to uncertainty when debugging, which is very influential.
When summing up the CCIE exam, the mentality should be relaxed. Many people think that the exam is very difficult, and they are not sure and confident. In fact, the exam is just the practice of the exam. A lot of practice is definitely no problem, but there must be a lot of practice. Each lab is integrated, and the stage of practicing the version is actually the fastest growing stage. It is much more than the growth of CCIE theory because many technical points and theories can only be understood in the process of practicing the version. It’s not the case that the meeting is not difficult, but the CCIE exam will only become more and more difficult today (Cisco itself also begins to control the pass rate), but the identity brought by the test is unparalleled. The sense of accomplishment that can be achieved in a short period of time and the joy that can be obtained through a long period of hard work are not the same. It is like playing a few hours to win a game and learning for a year. The sense of accomplishment and joy of CCIE is completely different. The latter kind of sweetness that has been hard to work for a long time will bring enough satisfaction and confidence to yourself.
There is no conflict between work and exams. I am also a person who has worked for nearly 10 years. The experience of learning the truth and the intensity of work is not as good as those of young people who have just entered the job. The memory is obviously not as good as before, but the advantage is that Relatively rich work experience and good understanding ability, this is actually very important, so for the veteran of the workplace, the test of CCIE is the icing on the cake, you have a strong learning ability, and it really takes years of work experience to become strong. And always maintain the attitude of learning, this is very valuable and must rely on time to accumulate. Some people say that there will be time conflicts between the exam and the work. If you want a smooth exam, you must temporarily stop the work and concentrate on the exam. I am not convinced at this point. I also took the CCIE during my work. To tell the truth, I did have the urge to quit my job and prepare for the exam. But after some delays, I did not quit my current job but chose to move on and use the work. Time and weekend time to practice as much as possible, finally stick to it, back Think of it also felt a lot of pay, at a later stage of the exercise will be enough time to implement the process of quantitative to qualitative change. However, if you are not satisfied with the current job, and you plan to change your job 100% after the exam, you can quit your job and concentrate on 1-2 weeks to sprint the exam. This is a multiplier.
About CCIE and HCIE exams, in domestic CCIE = HCIE, in global CCIE> HCIE, exam difficulty CCIE> HCIE. Datacom is just a foundation. Now the IT industry needs a talented person who is proficient in one and then familiar with many such talents, such as proficient in RS, familiar with wireless, Linux, VMware, DB, python, etc. So only one CCIE is not enough. This is just a starting point. The road behind it is still very long and needs to be shared.
